WELL-DRILLING APPARATUS.

Application filed April 12, 1923. Serial N0. 631,604.

To all whom it may concern:

Be it known that I, JEREMIAH R. S. Mo- CAR'ri-IY, a citizen of the United States, residing at Franklinville, in the county of Cattaraugus and State of New York, have invented new and useful Improvements in VVell-Drilling Apparatus, of which the following is a specification. I

This invention relates to improvements in well drilling apparatus and has for an object the provision of means whereby a number of wells may be drilled from a main station or main rig, means being provided whereby the drilling apparatus of each well may be either simultaneously or independent-ly operated.

Another object of the invention is the provision of a novel form of beam jack, whereby a maximum amount of power may be obtained for the drilling operation.

Another object of the invention is the provision of a multiple drilling apparatus which is simple in construction and efficient and economical in operation.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illlustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is a plan view of a multiple well drilling apparatus constructed in accordance with the invention.

Figure 2 is a fragmentary side elevation of the main rig.

Figure 3 is a horizontal sectional view taken on a line with the main operating shaft.

Figure 4; is a side elevation of the guide pulleys.

Figure 5 is an elevation of a one of the auxiliary rigs.

Figure 6 is a vertical central section of the same.

Figure 7 is a view on the line 77 of Figure 6.

Figure 8 is a perspective view of the beam jack shown in Figure 6.

Figure 9 is a fragmentary elevation illustrafging the manner of. mounting the beam portion of Figure 10 is an elevation of one of the beam jack cable guides.

Figure 11 is a fragmentary vertical sectional view illustrating a modified form of the invention.

Figure 12 is a diagram illustrating the manner of runnin a telephone cable from the main to theauxiliary rigs.

Figure 13 is a detail view illustrating a telephone cable supporting means.

Referring in detail to the drawings wherein like characters of reference denote corresponding parts, the invention which is designed for the operation of drilling a number of wells simultaneously and for controlling the drilling operations froma single station, includes a main rig A and auxiliary rigs B. While two auxiliary rigs are illustrated, one or more may be operated from the main rig.

The main rig which may be substantially of the standard type includes a derrick 15, a crown pulley 16 and a drilling cable 17 which passes over the crown pulley. This drilling cable has connected thereto one end of a beam 18 and the latter is pivotally mounted as shown at 19. The opposite end of this beam is connected to one end of a pitman 20 and the opposite end of this pitman is connected to a crank arm 21 which is carried bv a drive shaft 22. This shaft has mounted thereon a drive pulley 23 which is driven by means of a belt 24. from a suitable source of power.

Mounted in suitable bearings is a main operating shaft 25 and mounted for free rotation upon this shaft is a hoisting drum 26 around which the drilling cable 17 is wound after it passes over the crown pulley 16. The drum 26 is locked to or released from the shaft 25 by means of a clutch 27, the said clutch bein connected by means of a rod 28 with a hand operated controlling lever 29. The hoisting drum 26 carries a brake drum 30 around which operates a brake band 81 for the purpose of controlling the operation of the drum 26. This brake band is connected by means of a rod or connection 32 with a hand lever 33.

Also mounted for free rotation on the shaft 25 is a bailing drum 3% and this drum like e m 26 B ea e a brake drum 35 which is engaged by a band 36 and controlled by a hand lever 37. The bailing drum 34 is adapted to have wound thereon a sand line or bailingca'ble 37 which passes upward over a crown pulley 38 and is connected in the usual manner.

The shaft has secured thereon a pulley 39 which is driven from a suitable source of power by means of a belt 40.

By means of the apparatus just described,

the drilling and bailing operation of awell at the main rig A may be controlled and for the purpose of; operating and controlling the operation of the auxiliary rigs B, the shaft-25 has mounted thereon for tree rotation auxiliary hoisting drums 41 and auxiliary bailing drums 42. The drums 41 are controlled by clutches 43 which are similar to the clutches 27' previously described and are further provided with brakes 44 ofthecharacter previously mentioned. The bailing drums 42 are similarly equippedwith brakes 45 and are controlled by means around guide pulleys 49.

of clutches 46. By this means all of the hoisting drums may be locked with theshaft 25an'd simultaneously operated, or they may be selectively operated as desired. This isalsojtrue of the bailing drums.

The hoisting drums 41 have wound thereover'drilling cables 47 and these cables pass through guide yokes or pulleys 48 and They then pass through yokes or guide pulleys 50 and over crown pulleys 51 which are mounted at the tops of the derricks 52 of the auxiliary rigs B.

the beams 53 and for this purpose the latter are provided with spaced openings 60.

. The auxiliary beams 53 are operated from" the crank arm 21 of the: main rig A and for this purpose there is connected to this crank arm; one end of a cable, rod or similar member 61; The opposite end of this member carrie sa ring 62 which in turn carries-one or more rings 63, the number of the latter depending.uponthe number of auxiliary rigs. B; The rings 63 are connected to members 64 of a character similar to the emember 61', connection being efiected by thamemb'ersfiit areconnectedi to the jacks 56 of the auxiliary rigs. These jacks are The opposite. ends of provided with spaced openings 66 so that an adjustment may be effected to regulate the degree of movement of the jacks and consequently the movement of the beams 53.

F or the purpose of guiding the members 61 and 64 there is provided a plurality of cable guides C, which include a head 67 and legs 68 pivotally connected thereto. The head 67 has adjustably mounted therein a downwardly extending rod 69 which carries at its lower end a hook 70 for the reception of the members 61 and 64 so that the latter will be supported with a minimum amount of friction.

Also secured to the rings 63 are centering devices in the form of rods or cablesTO. These rods orcables are detachablyconnected to the rings 63 and their outer ends are similarlyconnected to anchors 71. This form of connection permits of ajbackward and forward movement otfthe members 61 and 64 during the drillingoperation and maintains the adjacent connected ends of these membersin proper relative position. In addition, either ofthe members 64 may be disconnected to cut out the operation of either of the auxiliary rigs B, while the connected members 61 and 64 will retain their proper operative relation.

The bailing drums 42 have wound thereon cables 72 which pass through yokes or pulleys 73 and around the pulleys 49 and. through guide eyes or pulleys 74 and over 7 crown pulleys'75, the latter being carried by the derricks of the auxiliary rigs B.

In Figure 11 there is illustrated; a, modified form of connection for the'beams 53 of the auxiliary rigs.- This comprises a branch cable 76 which extends from the member 64 and is connected as shown at 77 with the beam 53, meansbeing provided whereby this connection may be adjusted as necessary.

'In Figures 12 and 13 there is. illustrated means whereby a telephone line or cable may be connected between the main and auxiliary rigs. This comprises bracket arms 78 which are secured upon the upper threaded ends of the rods 69. These arms are provided with clamps 79 for holdingthe telephone wires,- while the telephone stations at the rigs A and B are indicated at S.
